12Gb/s Intel® RAID Controllers User Guide 5
The SAS interface uses the proven SCSI command set to ensure reliable data transfers,
while providing the connectivity and flexibility of point-to-point serial data transfers. The
serial transmission of SCSI commands eliminates clock-skew challenges. The SAS
interface provides improved performance, simplified cabling, smaller connectors, lower
pin count, and lower power requirements when compared to parallel SCSI.
The SAS controllers leverage a common electrical and physical connection interface that
is compatible with Serial ATA technology. The SAS protocols and the SATA III protocols
use a thin, 7-wire connector instead of the 68-wire SCSI cable or 26-wire ATA cable. The
SAS/SATA III connector and cable are easier to manipulate, allow connections to smaller
devices, and do not inhibit airflow. The point-to-point SATA III architecture eliminates
inherent difficulties created by the legacy ATA master-slave architecture, while
maintaining compatibility with existing ATA firmware.
PCI Express Architecture
PCIe is a local bus system designed to increase data transfers without slowing down the
central processing unit (CPU). You can install the 12Gb/s Intel
®
RAID Controllers in
PCIe computer systems with a standard bracket type. With these controllers in your
system, you can connect SAS devices and SATA devices over the bus.
Note: Some PCIe slots support PCIe graphics cards only; RAID controllers installed in these
PCIe slots do not function.
PCIe goes beyond the PCI specification in that it is intended as a unifying I/O architecture
for various systems: desktops, workstations, mobile devices, servers, communications,
and embedded devices.
